State legislators in Idaho are working to declare President Obama's health-care law "null and void" on the argument that states have the final say when their laws disagree with federal statutes. But critics argue that is a fundamental misunderstanding of the 10th Amendment to the Constitution.

Nullification – the legal theory that says a state can prevent enforcement of federal laws within its borders -- is the latest attempt to block Obama’s health-care law at the state level. And brings with it new controversies and considerable confusion. For example, supporters and opponents of nullification reference the same language in the Constitution.

"I believe that we have sometimes allowed ourselves to think that the federal government is the final say in everything," Republican Idaho state Sen. Monty Pearce, the sponsor of a nullification bill that will be introduced in the Idaho Legislature next week.

The ongoing fight over whether the Bible and other religious texts should be allowed in Idaho's classrooms is about to go before the Ninth U.S. Circuit Court of Appeals.

Officials at Nampa Classical Academy, one of the biggest charger schools in Idaho, began struggling with state officials over the issue shortly after opening in August 2009. The quarrel continued, even after the Idaho Public Charter School Commission closed the academy last summer, citing financial trouble. The school is now challenging the dismissal of its federal lawsuit against state officials who barred religious material as teaching tools in the classroom.

"Where it stands now is that the State of Idaho has banned the objective study of the Bible and all religious texts -- whether it's for history...literature...music or whatever it happens to be -- from being used at all," reports Alliance Defense Fund (ADF) attorney David Cortman.
